Application am my a,

My resent invention has reference to a' vulcamzer, and has forone of its objects the provision of a vulcanizer that dispenses with the employment of air bags and b whose 8 use a plurality of tires, tubes or the e may curved projections which are concaved, a

mold being arranged centrally and longitudinally in thetop of the body, together- I, with means, in-the nature of presser plates,

that are movable by screws into the mold and into the concaved sides of the ;body,

whereby a tire of the ordinary construction may be treated in the mold, while the concaved sides take care of tires, either of the ordinary or balloontype, ,whose side walls are to be cured.

A still further object'is the provision of a vulcanizer that includes a trou h-like body having a mold in the top thereo and having concaved side projections whose inner walls are'concaved, the'body being inclosed in a jcasin that hasopenin in the sides thereof for t 'e projecting si es ofthe body, said a0 casing being filled with asbestos or other non-heat conducting material but carrying removable heater coils arranged below the bottom of the body so the water in the body will be heated, the said body having its- 7 $8 sides provided with upwardly extendin downwardly arched arms from each 0 which is hung. a rod. or bar carrying a presser plate, the said plates being disposed 40 h2 1; influenced by screws toward such sides, the armssupporting therebetween. a support for another'screw' that operates an expansible presser of particular and novel construction which is arranged in-the mold,

and whereby tires can be treated in the mold or in the concaved sides of the bod i For a more definite comprehension of'the invention reference is to be had'to. the following specification and the drawings which,

ica-

site the concaved sides of the body and for the major'portion thereof, is filled wit 1m. lerlal I0. 181,187.

ings illustrate one satisfactory embodiment of the' invention, from which such. changes may be made as fairly fall within the scope of what is. claimed. a

As. disclosed by the drawings, my improved vulcanizer contemplates the em loyment of a metal block 1. The block is of trough-like formation and is designed to have received in the bottom thereof'a' quantity of water, indicated by the numeral 2. The top of the block provides a mold 3. The mold has its-bottom round in cross section and'its sides straight and spaced from the straight sides ofthe block proper. The mgofid'B 1s concaved orrounded longitudi- ..y-

referably, the lower corners of the block are rounded inwardly and the endsthereof are inclined from the said rounded corners, inwardly to the top of the block. The sides of the block are integrally formed with outwardly projecting portions 4 which are seg-; mental in form and which are concaved lo itudinallyas at 5.

e projections 4 pass through complementary shaped openings 6 in the sides of a casing 7. The projections thus hold the casing on the block. The casing has its ends inclined outwardl to its bottom and the base .or bottom 0 the casing, indicated by the numeral 8, is removable. The casing;

a heat retainingbpackin 9, but there are arranged in the ttomo the casing removable heater coils 10. The coils are attached ;to a suitable source bfelectricity which heats the water 2 of the hollow trough-like block 1 and which likewise heats the block itself. Arising centrally from the top of the block, at the sides thereof, there are outwardly arched arms 11. These arms are referably removably secured to the block y means 12. The arms are comparatively narrow, and the upper ends thereof have pins 13 passin transversely therethrough. he pins 13 a so pass through elongated openings 14 in hanger rods 15. Therods 15 are provided with other openings 16 disposed right-angularly with respect to the ogenin 14, and through the openings 16 t e en of the arms 11 pass. Each hanger rod has athickened portion through which there is a central elongatedslot or opening 17, and the lower end of each hanger rod. 15 has fixed thereon a laterally extending presser plate 18. The presser plates are disposed opposite the center of the concaved thickened or enlarged sides 4 of the body 1. Passing through the openings 17 there are screw members 19. These screws are also guided through openings in the arms 11 and engage with nuts '20 that are let in pockets 21 in the said arms. The screws have uper hand wheels 22 provided with hubs 23 'sposed opposite and engageable with the hanger arms. 0

As far as p it will be seen that tires to be treated may be received at either or both of the concavities 5 of what I have termed the side extensions 4. In reality these extensions are in the'na-' ture of lugs. The hanger rods 15 are freely hung from the arms 11 and are susceptible to vertical movement thereon. Thus, when the screws are operatedto influence the arms toward the tire to be treated, the presser plates 18 on the said arms" may be properly adjusted with respect to the part of a tire with which they are to engage.

Seated in depressions 24 in the inner and widened lower ends of the arms 11 above the pockets 21, there is a brid e plate 25. Threaded centrally through the p ate 25 there is a screw 26 that has an upper hand wheel 27. Thelower end of the screw has a ball rod which is swiveled in a block 28 that is centrally secured on the inner face of a concaved late 29. The screw 26 is also threaded throng an expander plate 30 and this plate 30 is in contact with segmental plates 31 whose lower and thickened ends rest in the sides of a concaved plate 29. The plates 29 and 31 provide the resser elements. which en ge with a tire to treated in the mold 3.

y the employment of my improvement it will be seen that at least three tires can be treated simultaneously. It will also be noted that I have entirely dispensed with the employment of air ha and from experience have found that t e screws which actuate the presser plates render the device easily operated and with the employment of only a red,

the description has progressed the part 3 as the inner mold of the device and have shown the same integrally formed with the block 1, the same may be separately constructed from said block, so that interchangeable molds may be employed. 'lVhcn, however, the mold is integrally formed with the block, fillers may be arranged therein to compensate for tires of different sizes. The operation of the screw 26 for the inner expander not only presses the plate 29 against the tire in the mold 3, but imparts a longitudinal movement to the plate 30, and the ends of this plate contactlng with the segmental plates '31 of the expander spread the same outwardly to force the side walls of a tire against the mold. Of course, the'device is provided with a suitable normally closed opening whereby water may be fed into the trough-like hollow block or body.

Having described the invention, I claim 1'. A vulcanizer comprising a hollow metal block having arcuate projections on the sides thereof which are concaved longitudinally to provide side molds and having an inwardly extending mold in the top thereof, presser plates movable into the central inwardly extending and the concaved side molds, and means for heating the block.

2. A vulcanizer comprising a hollow metal bod designed for the reception of water in the ottom thereof, said body having its sides integrally formed with arcuate projections which are concaved longitudinally, its to extending inwardly from its sides and cm thence downwardl merging into a round bottom disposed a ove the bottom of the block, the said concaved sides and central portions of the block roviding molds, hanger rods loosely s'uspen ed from the sides of the block, presser plates thereon, revoluble means engageable with the rods for exerting a pressure thereagainst for forcing the presser plates into the side molds, an expansible presser plate for the central mold, revoluble means for expanding the presser late in said mold, and means for heating the y.

3. A vulcanizin machine including a hollow metal block esigned for'the reception of water therein and having arcuate projections on the sides thereof which are concaved longitudinally and which provide molds, an
